LuxQuanta is a Barcelona-based quantum security startup founded in May 2021 as a spin-off from ICFO (The Institute of Photonic Sciences), specializing in quantum key distribution (QKD) systems. The company develops continuous variable QKD (CV-QKD) technology that provides ultra-secure data encryption and is easier to integrate into existing optical network infrastructures.
